Series IV PULSAR
The Series IV PULSAR series multi-gas NDIR analysers are available in 1, 2, 3, 4 or 5 gas channel configurations, offering high levels of performance and flexibility. Options include CO, CO2, CH4, NO, N2O, SO2, HCl and O2.
The latest PULSAR analysers have been developed to deliver outstanding levels of performance. With ultra-low drift they are ideal for low range applications and high accuracy measurements. The unique design of the detector prevents cross-sensitivity to other gases and removes the risk of contamination by particulate matter, so the instrument is ideal for a wide range of applications.

Remote connectivity
With 3G, 4G, GPRS, Bluetooth, Wifi and satellite compatibility, Series IV instruments each have their own IP address and run on Windows software. Consequently, users have simple and secure access to their analyzers at any time, from anywhere, making these instruments ideal for remote sites and for customers with multiple sites. Remote connectivity saves time and money, and creates new possibilities for enhanced reliability. Users (and Signal’s service engineers, on request) can monitor the status of analyzers remotely, so that timely service interventions can take place when required rather than on a timed schedule. This lowers the cost of ownership and reduces potential downtime.
Software
High levels of accuracy are achieved with advanced software, employing a 4th order polynomial, which ensures linearity of response. The analysers are supplied with remote interface software (S4i) as standard, which enables remote data collection and diagnostic capability. This is open source software designed to provide a wide range of functionality, including an option for users to add their own features if they wish.
User selectable ranges can be programmed to allow each range to have a calibration value entered and a relay inside the analyser can be used to select that calibration gas and auto-calibrate each range separately.
Optional touch-screen with datalogging
